Gastrointestinal bleeding has been observed in long-distance runners. We prospectively studied participants of the Eighth Annual Marine Corps Marathon to determine the incidence of gastrointestinal blood loss associated with long-distance running. Of 600 runners contacted, 125 (21%) returned a questionnaire as well as pre- and postmarathon stool specimens. Stool specimens converted from Hemoccult negative to positive in 29/125 (23%) of the participants, indicating that running the marathon was associated with gastrointestinal blood loss (P less than 0.001). The incidence of this conversion (negative to positive) was significant for both males (N = 68, P less than 0.001) and females (N = 57, P less than 0.05). Gastrointestinal bleeding appeared to be independent of age, race time, abdominal symptoms, and the recent ingestion of aspirin, vitamin C, or steak.
在长跑运动员中曾观察到胃肠道出血。我们对第八届年度海军陆战队马拉松赛的参与者进行了前瞻性研究，以确定与长跑相关的胃肠道失血发生率。在联系的600名跑步者中，125名（21%）返回了问卷以及马拉松赛前和赛后的粪便样本。29/125（23%）的参与者粪便样本潜血试验结果由阴性转为阳性，表明跑马拉松与胃肠道失血有关（P<0.001）。这种转变（阴性转为阳性）的发生率在男性（N = 68，P<0.001）和女性（N = 57，P<0.05）中均具有显著性。胃肠道出血似乎与年龄、比赛用时、腹部症状以及近期服用阿司匹林、维生素C或牛排无关。
